Re: How do you ventilate Layens hives?
Well, those commercial Lang hives have no under-frame space to speak off (often retro-mitigated by the under-frame racks, empty super box at the bottom, etc - for better moisture dissipation in winter). Also, a typical Lang keeper does not create an empty side air-pocket for better moisture dissipation.

The moisture removal (your concern) is achieved by
1)direct ventilation - up and out
2)dissipation to the drier volume of the hive due to moisture gradients - down and to the side
In reality, this is always some combination of #1 and #2 (and something else - say, wind exposure).
Long hives (unlike typical Langs) have better configuration for #2 (#1 still being a part of the picture) and so #2 is to be taken advantage off since you have it built-in.
Like I said, in my current setups I feel I allow for too MUCH ventilation in the cold season (subsequently, bees have to work harder to warm themselves - too much heat is lost from the cluster - energy is sucked away due to too much ventilation).
Will modify my follower boards to be tighter for this winter - there is too much drafting around them as it is now.
Regarding 1-2 visits per the year - I too believed into the story originally.
Now, I have to clarify - G. Layens was resident of Southern France or thereabouts - minimal care is needed for wintering - no care for the current mite situation either.
L. Sharashkin is in Southen MO (those pictures of his snowed hives - you just have smile at them - he really has no winter - I know, because I lived in the KC area for about 10 years).
Basically, if you are in the USDA 4 or bordering it - this will be more than 1-2 visits per year just so you can winterize the hives (end then undo it).
Also, L. Sharashkin must make it clear - 1-2 visits per a year are only possible if you do not have to deal with the mites at all (diff subject here) - not possible in the majority of locations.
